The central motor conduction to the relaxed muscles was studied in 30 normal volunteers using magneto-electrical stimulation (MES) of the central motor pathways. The results were compared with those obtained by the percutaneous electrical stimulation technique (PES) described previously. None of the cortical and spinal latencies (Lcor and Lsp, respectively) and the central motor conduction time were different between MES and PES in the upper limb muscles. In some lower limb muscles, however, the Lsps of MES were significantly shorter than those of PES. This was probably because the magnetic stimulation over the lumbar spinal column activated the motor roots at their exit from the spinal canal rather than the level of conus medullaris, at which activation occurs in the electrical stimulation.
